Symptoms
- No sound from Beam when TV is on
- Sonos app shows "No TV Signal"
- TV internal speakers still active
- HDMI ARC port not recognized
- Happens after new TV setup
- Music playback on Beam works fine
Recognize these? Here's what usually causes it.
Common Causes
- Incorrect TV audio output settings
- HDMI ARC/eARC not enabled on TV
- Faulty HDMI cable
- Outdated TV or Sonos firmware
- CEC conflicts
- Incorrect HDMI port used
Most fixes happen in the first 3 steps.
Some older TVs or certain brands may have finicky HDMI-CEC implementations. If you continue to have issues, you might need to experiment with disabling CEC features on your TV or external devices.

Step-by-Step Solution
Verify TV Audio Output Settings
Access your TV\'s audio settings menu. Ensure the audio output is set to \'External Speakers\' or \'HDMI ARC\' and that the digital audio output format is set to \'Bitstream\' or \'Dolby Digital\' (not PCM or Stereo). Also, ensure HDMI-CEC (or your TV\'s equivalent, e.g., Anynet+, Bravia Sync) is enabled.

Many TVs require you to explicitly enable the HDMI ARC or eARC feature in their settings. Look for options like \'HDMI Control\', \'ARC Mode\', or \'eARC Mode\' in your TV\'s system or sound settings and ensure it\'s turned on. Reboot your TV after making changes.
Use a High-Quality HDMI Cable and Correct Port
Ensure you are using a high-speed HDMI cable (preferably HDMI 2.0 or newer) and that it\'s connected to the correct HDMI ARC/eARC port on your TV. This port is usually labeled. Try a different HDMI cable to rule out a faulty cable.
Update TV and Sonos Firmware
Ensure both your TV and your Sonos Beam have the latest firmware. Outdated firmware on either device can cause compatibility issues with HDMI ARC. Check your TV\'s settings for software updates and your Sonos app (Settings > System > System Updates) for Beam firmware.
Power Cycle All Devices
Unplug your TV, Sonos Beam, and any connected external devices (e.g., cable box, streaming stick) from power for at least 60 seconds. Then, plug them back in in the following order: router, TV, Sonos Beam, and then other devices. This can resolve temporary communication glitches.
Quick Solutions
Still having issues? This is usually the deeper cause below.
This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.
If your TV has multiple HDMI ports, make sure you are connecting the Sonos Beam to the one specifically labeled \'ARC\' or \'eARC\'.
Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.
